Elon Musk is getting closer to being the real life Tony Stark, with his private rocket launch service SpaceX requesting permission from the government to launch a "massive satellite network that would provide high-speed, global internet coverage", reports Reuters.

SpaceX would eventually launch 4425 satellites, with Musk predicting it would cost at least $10 billion, and that was nearly two years ago when he first announced the project in January 2015. The latest details on the project include technical detailed of the proposed network, but there isn't a mention of the costs involved.

The financial backers of SpaceX include Alphabet's Google Inc and Fidelity Investments, who have pumped over $1 billion into Elon Musk's space company. SpaceX will launch around 800 satellites at first, which will cover the United Spaces, Puerto Rico, and the US Virgin Islands. SpaceX said in technical documents that it filed to the government: "The system is designed to provide a wide range of broadband and communications services for residential, commercial, institutional, government and professional users worldwide".

SpaceX will launch their satellites into orbits ranging from 714 miles to 823 miles, or 1150-1325 km above the Earth, with each satellite at the size of an average car. The satellites will be solar-powered, and weigh 850 pounds (386 kg).
